 Experiments in growing tobacco with different fertilizers in 



1894, E. H. Jenkins {Connecticut State Sta. Rpt. 1SD5, pp. 138-145). 



This is a continuation of work published in the Annual IJeiwrt of the 

 station for 1894: (E, S. II., 7, \). 1'07). The results are given of an examina- 

 tion of the fermented leaves grown in 1894, also the report of an expert 

 relating to the quality of 29 lots. Tabulated data show the fire-holding 

 capacity of the different lots, and the effect of fertilizers on the quality 

 and (juautity of tobacco is discussed. 



The fire-holding capacity of the leaf was increased in every case by 

 fermentation, and the tendency to char was not always associated with 

 small fire-holding capacity. 



The quality of the leaf raised on laud fertilized with cotton-seed meal 

 was somewhat better than when castor pomace Avas used. Nitrate of 

 soda was injurious to the quality of the wrappers. The total yield and 

 the percentage of wrappers was smallest with applications of stable 

 manure, but the quality was best. As to potash fertilizers, the largest 

 yield of wrappers was with ai^plications of double sulphate of potash 

 and magnesia, followed by the same with lime, by carbonate of potash, 

 and by wood ashes. 



Experiments in growing tobacco with different fertilizers in 



1895, E. n. Jenkins {Connect ient State Si a. Rpt. 1895^ pp. 146-150). — 

 This is a continuation of work published in the Annual Eeport of the 

 station for 1894 (E. S. E., 7, p. 208). Meteorological data for the season 

 are given, including temperature of the air and soil ; also the water con- 

 tent of the soil from daily determinations from June 17 to August 13. 



Cotton-seed meal, cotton-hull ashes, linseed meal, castor pomace, 

 nitrate of soda, double sulphate of potash and magnesia, carbonate of 

 potash, double carbonate of potash and magnesia, dry ground fish, 

 tobacco stems, wood ashes, and several brands of fertilizers -^ ere tested 

 in various combinations, and stable manure alone. The yields of unfer- 

 mented tobacco and the comparative fire-holding capacity of the tobacco 

 grown on the different plats are tabulated and briefly discussed. In 

 the gross yield of cured leaf and of wrapper leaf, castor pomace was 

 superior to cotton-seed meal. Where one-half the nitrogen in an api)li- 

 cation of 210 lbs. of nitrogen in the form of castor pomace was 

 replaced by nitrogen in nitrate of soda, the total yield of wrapper 

 leaf was greater. 



As to i)otash fertilizers, the largest gross yields followed apidications 

 of high-grade sulphate, both with and without lime. The largest yield 

 of wrapi)ers was from i)lats manured with carbonate of potash and the 

 double suli)hate of potash and magnesia. The fire-holding capacity 

 was least in tobacco manured with high-grade sulphate, followed by 

 that fertilized with low-grade sulphate. The plats dressed with fish 

 and nitrate of soda, fish and double sulphate of potash, and with stable 

 manure gave the smallest yields.
